ProjectsCopper Mountain MineAnnual Operating Statistics

The key development for 2015 was the first full season with our secondary crusher as a permanent solution to maximize production and improve overall efficiencies for the company. Secondary crusher construction was completed in August 2014 on budget and on schedule. We enjoyed record site operating costs and total operating costs as well as achieving record quarterly mill throughput of 37,500 tpd (Q3 2015). In Q3, 2017, Mill throughput averaged 41,158 tpd during the quarter, setting a new quarterly throughput record.
